New to BTC mining, just wanted to say hello, currently running a cheap rig, I have free electricity, getting about 480 mhps on the BitMinter pool.

Was running about 250 iMacs on the BitMinter pool a while back, but had to stop as boss was not overly happy...

Long story short, I got free power, boss says I can use mammoth server room at 18C constant temp, also use as much electricity as I want. 

I don't want to make a mining rig though, does anyone know where I can buy an FPGA setup for cash payment?
